TL;DR: Platform-wide device intelligence can connect repeated abuse patterns across merchants before losses compound, according to Fingerprint. E-commerce platforms then have to govern shared risk signals so fraud drops without adding needless friction at checkout.
Editorial analysis by NHI Mgmt Group, based on content published by Fingerprint: “How e-commerce platforms can build stronger fraud prevention at global scale”.
By the numbers:
- E-commerce sales are expected to surpass $6.8 trillion globally in 2025, according to Fingerprint.
Key questions
Q: Why do merchant-only fraud tools miss account takeover and promo abuse?
A: Because those attacks are often coordinated across many storefronts, and each merchant only sees a small slice of the pattern.
Q: What are the signs that platform fraud controls are too fragmented?
A: Common signs include repeated chargebacks from different merchants, the same device showing up in separate abuse cases, and inconsistent decisions for similar sessions across stores.
Q: How should platforms detect fraud across multiple merchants?
A: Platforms should correlate device, behavioural, and transaction signals across merchants so the same attacker cannot reset their profile by moving store to store.
Practitioner guidance
- Build cross-merchant risk correlation Connect device, account, and payment signals so a confirmed fraud pattern at one merchant can influence controls at the next merchant.
- Treat device intelligence as a shared control layer Use persistent device signals to support declines, step-up checks, and trust scoring across the full merchant ecosystem.
- Separate trusted and suspicious checkout paths Let low-risk sessions move with minimal friction while routing high-risk patterns into additional verification or blocking.
Bottom line: Merchant-siloed fraud controls leave a persistent gap when the same attacker can move across storefronts without a shared view of risk.

Platform-level fraud detection is becoming a shared trust problem, not a checkout feature. Once a platform supports thousands of merchants, the useful control is no longer merchant-by-merchant blocking but cross-merchant correlation. That changes the governance question from "did this store catch fraud?" to "did the platform learn from the last store?" Practitioners should treat fraud intelligence as ecosystem infrastructure, not point tooling.
A few things that frame the scale:
- U.S. fraud losses are projected to reach $40 billion by 2027.
A question worth separating out:
Q: Should platforms prioritise fraud prevention or checkout conversion?
A: They should govern both together. Stronger fraud controls are not useful if they create unnecessary friction for legitimate shoppers, and fast checkout is not valuable if it leaves the platform open to repeat abuse. The practical test is whether shared risk signals can reduce fraud while still letting trusted users move through checkout quickly.
